Letters Patent No. 85,47 7 dated December 29, 1868.

IMPROVED BEER-COOLER.

The Schedule referred to in these Letters Patent and making part of thename.

Be 'it-known that we, THOMAS L. RANKIN, of New Richmond, in the State ofOhio, and CHARLES IV. GRASSMUGK, of the city of Peru, in thecounty of LausefulApparatus for Cooling Malt-Liquors; and we do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same,.reference being bad to theannexed drawings, making a part of this specification, in which Figure 1is a perspective view,

Figure 2, the ground-plat; and

Figure 3 is a front view.

The nature of our invention consists in an apparatus by whichmalt-liquors can be more readily and economically cooled; and wherebythe atmospheric impurities, absorbed in cooling malt-liquors, can beexcluded atwill; and whereby the liquor ismade to melt all the waterthus made to a chamber, over which or underwhich the liquor is passed infinding its way out. of the cooler, thus giving the greatest possiblebenefit to the liquor from all the material used for the purpose ofcooling.

Figs. 1, 2, and 3 are sectional views of air-tight chamber, in which theliquor is cooled, securing the liquor s'tructive of malt-liquors, whencooled in the ordinary way of passing it down over copper-pipes, in theopen air, through which pipes a constantstream office-water is requiredto be kept flowing, in the proportion of one hundredbarrels of iceawaterto thirty barrels of maltllcpor; whereas it is claimed that, by ourinvention, the same number of barrels of liquor can be cooled withoutthe expense of pumping the one hundred barrels of water for making theice-water, and with onehalf the amount of ice required in the ordinaryway.

Fig. 1, a a is an inclined floor, over cooling-chamber,

which the cold is applied from above, either by placing ice alone onsaid floor, or refrigerating-mixtures.

Fig. 1, c c is pipe, that conducts the ice-water from floor a a toreceiving-chamber f f.

Fig. 1,7) I) is end of distributing-pipe, which extends each way fromsupply-pipe d, minutely perforated, from which the liquor is thrown anddistributed on the cold plane of the first co0ling-pan..

Fig. 1, (l, supply-pipe, coriducting liquor from vat to cooler.

Fig. 1, e e, galvanized iron cooling-pans, (more or less in'number,)over which the liquor is passed, in minute streams, and thrown into thecold air as many times, and thus conducted over a succession ofdripping-pans,

at the lower side, through which the liquor passes to the next pan, witha fall of about one and one-half foot from pan to pan, until it reachesthe' galvanized iron gathering-floor g g.

These pans, being made of good conducting-material, will in nowiseobstruct the natural currents of heat The pans to be of a size,ordinarily, to extend twothirds the way across the chamber; size ofpans, ordinarily, to be from three feet by eight feet, to four by six.

Fig. 1, g g, inclined gathering-floor, on which the liquor falls, andpasses over to outlet h; this floor to be made of galvanized iron orother good conductingmaterial, and is the top covering to ice-waterchamber ff, the water of said chamber being immediately in contact withthe iron of said floor, over which the liquor passes, finally givingentire and complete bensaid chamber that the minutest sheet of liquor,in

passing through, will be in contact with the cold iron at the bottom ofthe chamber, thus obtaining the entire benefit of all the ice that ismelted in the opera tion, in the simplest, cheapest, and most compactmanner possible.

outlet for beer; a, outlet for drawing oft" ice-water from chamber.

The whole of the foregoing-described metal chamber, containing thecooling-pans and ice, to be encased in a wooden wall or other material,constructed with a space, one foot or more, around said chamber, saidspace to be filled with some good non-conducting substance, with thickpacked doors, toclose over the airtight metal door of chamber.

. What we claim by our invention, and desire to secure by LettersPatent, is-- 1. An air-tight chamber for cooling beer, provided with aseries of trays of galvanized metal, which ex-c tend obliquely beyondthe vertical centre, from one side of the chamber towards the other, inopposite directions, one above the other, and. having their endsperforated, all substantially as set forth;

2. In combination with the above, we claim the inclined ice-chamber a,over said trays, which communicates with a vertical chamber, 0, leadinginto a coldwater space, f, under the trays, and so formed that itsnarrowest part is near the chamber 0, and with a conducting-pipe, b, forthe overflow, all substantially as shown and described.
